To find the total number of homework problems solved, we need to multiply the rate of solving problems per hour by the total time spent.

Since the rate is given as 26 problems per hour and the time spent is 2 hours 30 minutes, or 2.5 hours, we can multiply these two values:

Total number of homework problems solved = Rate of solving problems per hour x Time spent
= 26 problems/hour x 2.5 hours

To calculate this, we multiply 26 by 2.5:

Total number of homework problems solved = 65 problems

Therefore, the student solved a total of 65 homework problems in 2 hours 30 minutes at a rate of 26 problems per hour.
